Stationary Waves. Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave. When reflection occurs at a free end, there is no reversal of phase. i.e., a crest returns as a crest and a trough as a trough.
4.A longitudinal wave can be produced in a solid, liquid, or gas while a transverse wave can be produced in a solid and on the surface of liquid. 5.An example of a longitudinal wave is the primary or P-wave in an earthquake while an example of a transverse wave is the secondary or S-wave in an earthquake. 6.A transverse wave is made up of crests and troughs while a longitudinal wave is made up of compressions and rarefaction.
